Agricultural research boost: PAU secures Rs 4 crore GoI project for predictive breeding of guava
The project focuses on precision-driven predictive breeding in guava, a fruit often referred to as the "apple of the tropics" due to its high nutraceutical value.
The initiative, titled "Pangenomics and SNP array development for mapping genetic factors controlling nutraceutical and processing traits in guava (Psidium guajava L.)", aims at enhancing guava breeding through advanced genomic tools. Spanning five years, the project is designed to improve fruit quality, shelf life, and processing traits in guava varieties cultivated across India.
PAU boasts a rich germplasm collection of guava, featuring valuable traits such as colored skin and flesh, low seed count, soft seeds, and extended shelf life. These traits are central to the university's breeding priorities, which seek to increase the commercial appeal and nutritional value of the fruit.
The research team comprises 10 scientists from PAU, led by Dr Amandeep Mittal as project coordinator and principal investigator-I, and Dr Naresh Kumar Arora as principal investigator-II.

The team also includes Dr Manav Indra Singh Gill, Dr Parveen Chhuneja, Dr Inderjit Singh Yadav, Dr Rajbir Singh Boora, Dr Rimaljeet Kaur, Dr Kirandeep Kaur Kang, Dr Pawan Kumar Malhotra, and Dr Daljinder Singh as co-principal investigators.
It will focus on improving the guava genome of the popular Allahabad Safeda variety, generating a pangenome of Indian-origin guavas, and developing a SNP (Single Nucleotide Polymorphism) array to facilitate predictive breeding.
This will enable selection of progeny with desirable traits such as increased sweetness, reduced seed core, soft seeds, and anthocyanin-rich flesh—traits that are in high demand among consumers and processors.
The team emphasised that marker assisted selection (MAS) will play a key role in reducing the time, cost, and space required to develop new guava varieties. MAS allows breeders to identify and select plants with specific genetic traits early in the breeding process, making it a powerful tool for accelerating crop improvement.
PAU vice-chancellor Dr Satbir Singh Gosal congratulated the team for securing the project and praised their commitment to solving key challenges in fruit crop production. Dr Ajmer Singh Dhatt, director, research, and Dr Rishi Pal Singh, registrar, also lauded the team's efforts in advancing biotechnology-based solutions for farmers.
Dr Yogesh Vikal, director, School of Agricultural Biotechnology, and Dr H S Rattanpal, head of fruit science, commended the scientists for their outstanding achievement, calling it a milestone in PAU's research journey. This project is expected to significantly contribute to the development of elite guava cultivars with improved nutritional and commercial traits, benefiting both farmers and consumers across India.

The potato's secret past: Scientists uncover ancient botanical romance that changed the world
A team of international scientists has finally cracked a long-standing evolutionary mystery about the origin of potatoes. According to new research, the modern potato owes its existence to a rare natural hybridization event that occurred approximately 9 million years ago in South America , between tomato-like plants and potato relatives known as Etuberosum . This ancient interspecies union resulted in the first tuber-forming plant, giving rise to the modern potato, one of the world's most essential food crops.

Morphologically, modern potato plants appear nearly identical to Etuberosum species found in Chile, plants that do not form tubers. However, genetic studies suggested potatoes are more closely related to tomatoes. To resolve this, the research team, led by Sanwen Huang of the Chinese Academy of Agricultural Sciences, analyzed an extensive genomic dataset, 450 genomes from cultivated potatoes and 56 from wild relatives. This effort represents the most comprehensive genetic survey of wild potatoes ever conducted. Live Events They found that all potato species carry a balanced combination of DNA from both tomatoes and Etuberosum, indicating a one-time hybridization event that led to the development of the tuber, a nutrient-storing underground structure that radically enhanced the plant's adaptability. The genes behind the Tuber This evolutionary innovation came down to the merger of two critical genes. The SP6A gene, inherited from the tomato lineage, acts as a "master switch" to initiate tuber formation . Meanwhile, the IT1 gene from Etuberosum controls the growth of the underground stems that develop into tubers. Together, these genes gave the hybrid a powerful advantage: the ability to survive harsh Andean environments by storing nutrients underground, a trait that also enabled rapid reproduction and expansion. Climate and evolution collide The hybridization event coincided with the uplift of the Andes Mountains around 9 million years ago, which created a variety of ecological niches. Potatoes, with their newly evolved tubers, quickly adapted to high-altitude, cold, and dry conditions, environments where other crops could not thrive. Tubers also enabled a form of asexual reproduction. Potatoes could reproduce clonally, growing new plants from buds on their tubers, an evolutionary shortcut that allowed rapid spread and diversification. Today, more than 100 wild potato species exist, though not all are edible due to natural toxins. From ancient hybrid to global staple The potato was first domesticated roughly 10,000 years ago in the Andes and has since become the world's third most important staple crop, following wheat and rice. It now feeds billions, especially in areas with short growing seasons or poor soil conditions. Understanding the genetic origins of the potato could have major implications for agriculture . With climate change and increasing pest pressures threatening global food security, scientists hope to use these insights to develop more resilient, fast-growing potato varieties. Huang's team is already exploring ways to reintroduce tomato genes to engineer potatoes that reproduce via seeds rather than tubers, potentially increasing genetic diversity and disease resistance.
